The story begins with Asuna and Kirito from Sword Art Online being on a picnic with Yui, looking for a spot.

Kirito is there attacked by Accel World's Black Lotus, who was hired by a witch named Persona Vabel as a diversion while she managed to seal away Yui in plans to start an apocalypse.

Sword Art Online is a team-based game (with all voiced dialogue in Japanese with English subtitles[4]), where any of the three members can be switched at any time, each with their own attacks and abilities.

[7] Inspired by Sword Art Online: Lost Song, combat consists of melee (Accel World characters), learning skills, and occasional flying for aerial combat (Sword Art Online characters).

[10] Upon its release, the game was met with "mixed or average reviews" with an aggregate score of 64/100 for PlayStation 4 on Metacritic.
